Jerry, Thanks for your good advice! Hans

Thanks, Jerry. Is it ccw to richen and cw to lean the idle mixture? How much should I turn the disc before I can expect any difference? What is the total range of the disc? 1 turn? A lot of questions here, but I think the manual doesn't say much... Hans

Hi. Last weekend I ran my Lap Cat III w/K&B 11 outboard engine for the first time this summer. I had to retune the engine, because this was the first time I ran it on 25% nitro. I started out with the main needle 3 1/2 turns out as suggested, and leaned it in from there. I gradually closed the...

Re:Idle adjustment on K&B11 carb Thanks for all your help! Hans Jacob

Idle adjustment on K&B11 carb Hi I have a quite new k&b11 engine. The carb doesn't have an idle screw, but an idle DISC(low speed disc, as it is called in the manual). Today I wanted to richen the idle mixture, and I turned the disc 1/2 turn ccw. Then I wanted to check how many turns out the...

Jerry, Thanks for your help. Thanks to this community for being here and all you guys on the board who answer questions. Hans J

Re:K&B11 tuning problems Again, thanks for your replies. I am going to try a smaller prop, and purchase fuel with a bit more nitro in it. Your help have really been appreciated. Love you already...

Re:K&B11 tuning problems Hi Mark Thanks for your reply. Maybe I should try a smaller prop... By the way, your Solution looks very nice!Is it powered by a 11cc?

Re:K&B11 tuning problems Hi GTR Thank you for your quick response.It sure gave me some answers. I don`t feel that confused anymore. Thanks! The prop shaft is about 3/16" above the bottom of the sponsons, and I use a Prather 245 prop. Should I try another setup(lower/raise engine or change prop)?

K&B11 tuning problems ??? I have a Prather Lap Cat III with a K&B11. Last weekend I was running the boat, in order to tune the engine properly/make the boat run as fast as it is up for. But I had some problems understanding what was going on: As a starting point, the main needle valve was set...
